At this point the dough can, and should be, chilled or frozen. If making cookies in the near future, divide the dough into 2 balls and roll each out to 1/4 to 1/8-inch thickness between large pieces of parchment paper. Refrigerate for at least 1 hour. Or freeze the dough balls, wrapped in plastic wrap and a freezer bag, for up to 1 month. To thaw, leave in the refrigerator overnight then proceed with the recipe.
